I was able to completely turtle the boat last Sunday, as I went on a reach, the boat went over and sent me for a swim. Because of how hard the wind was blowing the boat was blown away from me, and went all the way over before I could even get back to it. Basically the tramp acted like a sail, and submerged the mast and forced the bob under. Like what was said earlier the boat is just as happy upside down.
